SO first off I'm still new to this forum site (so hello!) but i'm not new to PUA, I've been practicing for quite some time, but have hiccups every now and then. Hopefully you guys can help a brother out.
Here's the situation....
Tonight I was supposed to hang out with a girl who I used to work with lifeguarding, and who I saw around high school (when I went to high school. I am 19 now, turning 20 september of this year) It all sparked when she came in to a best buy while I was working there, and saw me. I gave her a hug, we caught up a bit, and then exchanged numbers.
After she left we then began text game, in which I wasn't too bad in. However, this went on for about 2 weeks until I was actually able to hang out with her.
Today is the day we were supposed to hang out, after 6pm. She was at the doctors getting an infusion.
*dt= Down Town
Me: I'm giving you five minutes to get ready
Her: I won't be home for a while :$ I'm getting my infusion
Me: Oh s***, That sounds dangerous. What super powers do you get from that?
Her: To read people's minds hehe
Me: Oh yeah? What am I thinking of 
Her: Food?
Me: You get points for creativity (I was actually eating at the time, and was thinking the same, but you should ways answer with the opposite response, and so I did)
Me: Well anyway, let me know what's going on because people are asking me to come dt tonight
Her: Sorry, that's what I was thinking about :$ and I don't feel like doing anything tonight, I'm not feeling too well and I have a headache. It's not easy to have super powers :$ have fun downtown!
Everything became a bit cloudy for me with the last text, and I'm not sure what to say next. I do want to see her again, but I'd like to create some more dhv spikes, and turn the table some more. Please note that she is 18 years old, so the game might work a tad differently. I noticed that last text was much more juicy when i dropped the DHV/ftc text to show her that I have s*** to do with other people (socialproofing), so tell me what's up. (she didn't reply to my "You get points for creativity" for about an HOUR or so. I only received a response 5 mins after i sent that last DHV/FTC text)
This was all very frustrating because I spent a large amount of time getting ready, and not being able to do other things as I "knew I was going out tonight"
Should I just ignore her for a long time? Give a short reply of some sort? We've exchanged quite a lot of texts, so perhaps I should give it a break, and not say anything. Build my DHV, and see what happens? What if I just texted her "Thanks" ?
Keep in mind that legal age in Canada is 19. I can go dt to clubs and such while she can not.
EDIT: I felt I should say something to her. So an hour later, I said "Thanks. Get better."
Thanks in advance. Love you all.
